C AMP non rnomno'rnve TIRES.

T0 aZZwh-om it may come m: 7 Be it known that' 1, CHARLES TV. (1. AL- LENDER, a citizen of the Uni-ted States, re-

siding at Denver, in the, county of Denver and State of Colorado, have invented certain new and useful improvements in Clampsior Protecting Tires, of which the following is a specification, reference being had to the accompanying drawings. I

It has been found that in making long trips in automobiles, the tires are subjected to considerable wear, thereby greatly short (eni-ng the life of the tire. This ISMPELIUCIP larl'y true after the tire has become partly worn.

Therefore, it is the purpose of the present' invention to utilize cast off tires, "for protecting those that are in use, For instance, tires which are three inches in diameter may be covered by a cast 10a tire, which is ordinarilythree and one-half inches in in fact the cast 0E tire has its shown, thereby leaving projecting parts of its clincher flanges, Which will be engaged by clampingmeans to hold the protecting cast oli'tireon the usedtire- The reason for cutting away the clincher flanges in this manner isv to permit the cast off tire to be stretched over the used tire, \vhile'the latter is in a deflated condition. y 1 g In order to hold the protecting tire in place on the used tire and to hold the adjacent severed. ends together, the present invention has for vanother purpose the provision of an improved clamp, which engages with the telly, and consists o'f'one section ing the clincher hook so that it may engage having clincher hooksto engage one of theclincher flanges of the protecting tire, in comlolnation wlth anothersectlon havlng clincher hooks to engage the opposite clincher flange of the protecting tire, there being a connecting olasp pivotally, carried by the first section andadjustably engaged by the second section, to holdlthe sectional clamp in place.

Still another purpose has to do wrthspacon either side of the joint between-the adjacent severed ends of the protecting tire, to hold the'adjacent ends securely together and to prevent displacement.

A further purpose consists in providing the clinchersection of the clamp with elongated spaced arms to straddle-any"0ne of I applied;

position, prevent its creeping, as Well as Specification of Letters Patent. Ffltenfd I Application filed December 3, 1921, Seria1 No. 519,629'.

' the spokes ofthe wheel, ;to'hold'the clamp in preventing creeping of the protecting tire.

A still further purpose has to dof withjso constructing the connecting clasp,that when it isdisposed, in: a position. to draw the two .7

sections ofthe clamp into secure'engagement" with the opposite clincher flanges of the protecting tire, the points of. engagement of hooks of one section with the clasp are disposed at positions tocone side oit the pivot" of thejclasp, When-the clasp is disposed in i a locked position. In other -Wofds the points of engagement. of one section with the clasp are disposed to: ;one side ot a linea-n passing through, the pivot of the clas where one sectionengages one of the clincher flanges ot the protecting tire, thereby pre venting disconnection of the sections oi the clamp-,.that is, when the claspis moved tea locked position. i iengagement with the folly. 2

The invention further aims to sharpen the clincher hooks of thefsection to. the clamp, so as to firmly engage the-opposite clincher flanges of the protecting tire,-to insu re hold-' ing the protecting tire" in position. i i

Also it is the aim to provide clamp sections hich may beinexpensively manufactured i and sold at a fair profit, and still further the mvention has to do with constructing the clamp sections and the clasp, so each part may be made by one stamping,-or p by means of a drop forge method While the design and construction at pres eut illustrated and set forth are deemed preferable, it is obvious that as ya result of 21;

In the drawings:: 1 g Figure 1 is a view in side elevation of a portion of a wheelfzfell-y and its IlIH ShOW- ing the tire to be protectechand the protect? ing tire in place,- and illustrating the clamp Figure 2 is a sectional View on line2 2 'of 1 Figure 3 is an enlargeddetail perspective its bearings.

namely the'one which straddles the spoke oi the wheel;

Figure 4 is a detail perspective View of the other clamp section;

Figure 5 is a detail view of the clamp, which is disposed relatively to the other clamp sections, showing how all three parts may be easily assembled;

Figure 6 is a detail View in side elevation of an entire wheel, showing a plurality of clamps applied, with certain of the arms 1 engaging certain sides of the spokes, while other of said arms ll engage certain other opposite sides of the spokes of the wheel.

Referring to the drawings, 1 designates the telly, 2 the spokes, and 3 the rim, which may be mounted upon and secured to the telly in any suitable manner. The usual. tire d which is designed for use on the rim has its clincher flanges 5 in engagement with the usual clincher flanges 6 of the rim, rod

7 denotes the inner tube of the tire.

*In order to protect the usual tire l, which is in use, a protecting tire 8 is provided. This protecting tire is constructed from cast Oil tires, and the opposite clincher flanges thereof are cut away at intervals, as shown at 9, thereby leaving projecting clincher flanges 10. The purpose of cutting away the'clincher flanges of the protecting tire, is to engage said tire to be stretched suiliciently, so that it may be fitted. over the used tire.

' The protecting tire is designed to be oi diameter in cross section, large enough to engage over the tire in use. Furthermore the protecting tire is designed to be large enough in its radius to lit over the used tire TVhen the protecting tire is applied, its clincher flanges 10 are disposed so that their inner portions rest upon the clincher flanges 6 ot the rim, as shown clearly in Figures 1. and 2 especially the latter.

The clamp for holding the protecting tire in position comprises a dominant clamp section 11, which consists of a plate 12 provided with clincher hooks 13, which have their ends sharpened or pointed, so to engage with one of the clincher flanges l0 oi the p ecting tire. V are the arms 14:, which straddle one the sp kes 2 of the folly, in fact the arms 14: en .z'e on the inner face of the telly on either :le oi the spoke, thereby not only prevent creeping of the clamp, but also prove; creeping of the protecting tire. These lat terminate in eyes 15, in which the ali pintles or trunnions 16 of the clasp 1..

The eyes 15 are slig y open i order to permit the trunnions 16 of the c 17 to .stop in their bearings, when the c is connected. In this way the clasp or easily and very quickly detached, when if mantling the protecting tire. This 17 is preferably angular as shown, though it Projecting from the plate 1:.

may be otherwise shaped, so that the lateral part 18 may engage the side otthe telly when the clasp is in a locked position. The opposite edges oi the clasp adjacent where the pintles or trunnions 16 are formed, are provided WliJllSllOlllClGIS 19, which are engaged by the hook lugs 20 of the other clamp section 21. Adjacent where the hook lugs 20 are formed, the clamp section 21 is bent at an obtuse angle as at :22, so as to engage over the pivoted. end of the clasp, when the clasp is in a loc red position. The hook lugsAO are spaced sutliciently' to straddle the reduced portions 180% the clasp. The clamp section 21 has spaced clincher hooks which are sharpened to engage firmly in the other clincher flange 10 of the protecting tire, and are spaced sul'liciently to insure a wide range 01 engagement with the protectwith the shoulders 19 are disposed on one side of the ournals oi the trunnions l6,

namely at a pointadjacent the telly of the wheel and on one side of the ll11Q-(,Z (L, there by drawing the protecting tire tightly in place and in engagement with the tire which is in use. I p

in order to apply the protecting tire 8, the tire l which is in use is first deflated, then the protecting tire is stretched due to the cut away portions 9 of the clincher flanges 10 sufficiently to allowit to be fitted over the used tire 4, after which the tire 4: is then properly inflated. The clamps are then applied with the clincher lugs engaging-the projecting clincher, flanges 1O of the.

enable the protecting tire and the flange to be properly positioned, and after properly positioned the tire l is entirely inflated, then the clamp will draw and hold the protecting tire iirmly in place. As shown in Figure 6 there are several clamps provided, and it will be noted that the dominant clamp section 11 has its arms 14- engagiiig one side of certain of the spokes 2 of the wheel, while the arms 1% of certain other of the clamping sections 11 engage corresponding. opposite sides of other of said spokes 2 ot the wheel, thereby in this way preventing the protecting tire 8 from creeping. From the toregoing, it is obvious that an ini nroved form or clamp is provided, for attaching 'i'oads are encountered, thereby prolonging the life of the tire, and at the same time acting to prevent puncturing the main tire,

tosome extent. This is due to the fact that the member which may puncture the tire will have to pass throughthe wall of the protecting tire and then through the main tire, in order to reach the inner tube.

The invention having been, set forth,

between the sides of the U-shaped clamp section, said clasp having pintles, the sides of the U-shaped clamp section having bearings for the reception of said pintles, the auxiliary clamp section having spaced hooks, said clasp having a reduced portion of a width equal to the space betweensaid hooks, said clasp having shoulders'caus ed to be formed by thereduced portion and beingengaged by said spaced hooks, whereby upon moving the clasp so that its-reduced portion. may
